That works now. :)
I compared your file with the original using Winmerge, so i can see where the code blocks have been moved.
I'll now have a play with the pages I just created for Eric, to try and 'fix' them.
All the best
I moved the code blocks in multi_delete_blank_B as in Sally's posted sample, and changed the code on the submit button and the post trigger block, so that there was no appended text, and it now works successfully!
Attached is fixed delete page
